Rolling CF7 back to 5.19 worked for me. submissionID is now working again.
I deactivated or removed some other CF7 plugins we had installed and then tried going back to CF7 5.2 and the submissionID stopped incrementing again.
Rolled it to 5.19 again and the submissionIDs are incrementing again.
Same issue here. Received 5 form submissions in the last 12 hours, all have submissionID of 1.
I’m having the same issue.
Adding the files that PDF Embedder suggested to the Exclude section did not resolve it. Actually already had them listed in there before their latest update caused this issue.
I had to disable the JS caching features in WP Fastest Cache. I unchecked “Minify JS”, “Combine JS” and “Combine JS+” and now the embedded PDFs work.
Hope this helps, @periago
